About Me

I am a psychometrician who works on K-12 assessments for various states at Cambium Assessment. I earned my Ph.D. in Psychometrics and Quantitative Psychology from the University of Notre Dame in 2025, where my work focused on response-time modeling, non-parametric item response theory, and differential item functioning. More broadly, I am interested in improving measurement accuracy and fairness through process data and modern statistical methods. You can find my CV here.
